Panagon IS and CS Communications : CS (Content Services) uses default MS SQL Server Panagon IS and CS Communications : CS (Content Services) uses default MS SQL Server or Oracle protocols. : IS (Image Services) uses File. NET Courier protocols. : Web Services uses these protocols to communicate with back-end libraries, and uses http or https to communicate with clients. 1

What is File. NET Courier? : Courier is a protocol family that sits on What is File. NET Courier? : Courier is a protocol family that sits on top of the client & server’s IP stacks. : “Client” refers to Panagon Web Services, Panagon IDM, or WFD thick client software. : Clients send requests to the IS servers and get responses using Remote Procedure Calls or RPCs. : Courier is made up of COR, PEP, & NCH. 2

Courier Protocols : COR – Courier Remote Procedure Calls : NCH – Network Clearing Courier Protocols : COR – Courier Remote Procedure Calls : NCH – Network Clearing House * : PEP – Packet Exchange Protocol * * These last two are UDP based. Since many client’s security policies restrict the use of UDP, Image Services can be run without them. 3

Courier Remote Procedure Calls : Connection oriented – runs on top of server TCP Courier Remote Procedure Calls : Connection oriented – runs on top of server TCP port 32769 through COR_Listen or OCOR_Listen. : Acts as a foundation for request and response sequences, or RPCs. : Connections range from nine frames to several thousand frames in length. 4

Packet Exchange Protocol : Used by IS Document Services (ds_notify) to notify a client Packet Exchange Protocol : Used by IS Document Services (ds_notify) to notify a client that an object has been retrieved from optical and is ready for display. : Used by clients to discover the NCH Server, unless they are configured to use a “ 4 -part” NCH domain name. : PEP runs “on top” of UDP – port 32770 for NCH, variable port for ds_notify. 6

Network Clearing House : Acts as name-to-address database for all File. NET IS systems. Network Clearing House : Acts as name-to-address database for all File. NET IS systems. : Can be found using PEP broadcast at client startup, or “directed” PEP if 4 -part NCH name is used. : NCH is accessed via COR RPCs once a client is logged on. : NCH_daemon on Root “listens” on UDP port 32770. 7
